A novel MLI topology with reduced power switches

Abstract

The Multilevel inverter is a most attractive inverter in high powermedium voltage energy conversion. It can produce switched waveform with free of or reduced total harmonic distortion. It can produce most sinusoidal voltage with increase in number of output level. But increase in level that requires more number of switches which lead to increase the cost, space and complexity in control. In this paper, we proposed new multilevel inverter topology with reduced number of switches which reduce the size and cost considerably. Also the comparison of work with the existing types of multilevel inverter topologies is addressed. The validation of proposed inverter is verified with simulation result using MATLAB. The proposed method will reduce the limitation of multilevel inverter for real time application and viable as a commercial product.
